IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 56,289, dated July 10,1866.

To all whom it may concern:

Be it known that I, D.G. STOVER, of Lanark, in'the county of Carroll andState of Illinois, haveinvented a new and Improved Cultivator; and I dohereby declare that the following is a full, clear, and exactdescription thereof,

which will enable. those skilled in the art to spondin g parts.

A represents a rectangular frame, which is mounted on two wheels, B I),and has a draftpole, 0, attached to it, and D D are two plowbeams, thefront ends of which are fitted loosely on a shaft, E, at the under sideof the front cross-bar, a, of--the' frame A. r

The plow-beams D are connected in front of the axle F by links G, witharms or cranks b at the end of a shaft, H, said shaft having itsbearings at the under side of the axle F, and provided at its centerwith a foot-piece or treadle, I, which projects behind the axle.

The beams D D have each an upright, c, attached, and the upper ends ofthese uprights are connected by a cross-bar, d, to which two pendentbars, J J, are attached by bolts 0, the

latter passing through any of a series of holes in plates fat the upperends of bars J, in order to admit of the latter being adjusted higher orlower, as may be desired.

The two bars J J are connected by two bars, K K, the latter beingsecured to the former by pivots, and the bars K K are connected togetherby a pivot, 9, one bar, K, projecting considerably beyond K to serve asa handle, by operating which the bars J J may be moved toward and fromeach other.

The lower ends of the bars J J are attached to plow-beams L L, the frontends of which are secured to the front cross-bar, a, of the frame A byuniversal joints.

The rear parts of thebeams D D L L have plow-standards M attached tothem, as follows: The upper parts, a", of these standards at one sideare made of semi-cylindrical form, and are fitted in concave sockets N,attached to the beams by bolts It, said bolts also securing thestandards to the socketsby passing through slotsi in the standards, saidslots being of V shape, or gradually increasing in width from the outerto the inner sides of the standards, as shown in Fig. 4. Thisarrangement, it will be seen, admits of the plows N, which are securedto the standards, being turned so as to throw the earth either from ortoward the plants, as may be desired, and said arrange: ment possessesthe advantageof allowingthe standards to turn back inease of thebreaking of the braces j, the sockets N turning on the bolts h. 7

It will be seen that the plows of the beams L L may be readily movedlaterally to conform to the ,sinuosities of the rows of plants byoperating" the lever K, and that all of the pl ows may be raised out ofthe ground when required for deposing the treadle I.

The device is extremely simple, and there are no-parts liable to get outof repair or become deranged by use.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut-- The arrangement of the uprights 0 c andbar at withthe pendent bars J J and plowbeams D D L L.
